Noise reduction

Silence for you and your neighbours

The Silentbox noise cover is an ideal solution for reduction of noise emerging from your heat pump or air conditioning unit.

Increasing interest and extent of use of the heat pump units and cooling units being installed particularly in the residential areas often results in demand for their attenuation due to excessive noise level generated by the units.

Silence for you and your neighbours
Retaining of thermal power

High attenuation effect

Retaining of thermal power

Silentbox is distinguished by high attenuation performance and easy installation without breaching the technical parameters of the unit.

The silencing cover will improve the environmental comfort not only for the user but for the surrounding environment as well. Its flexible structure permits directing of the air flow at input and output in multiple directions, and the options for use are expanded thereby. Condensate is drained through permeable section of the base floor frame of the noise cover.

Discreet solution

Unexpectedly high effect

The Silentbox cover shell is normally manufactured from RAL 9010 varnished metal sheet, then filled in with high quality sound insulation material with resistance to weather conditions and fire class B according to ČSN EN 13501-1. The cover base frame is made from bent zinc-coated metal sheet without any surface paint. The suction and exhaust spaces are separated by a technical canvas so that no air mixing does occur.

Unexpectedly high effect

Rating and designing

To achieve maximum effect

The noise cover for the heat pump or air conditioning unit is designed with respect to its size, cooling air need, and fan pressure reserve.

Silent / Supersilent

In addition, the cover size depends on type and size of the unit, and last but not least on volume of the ventilation air. The pressure drop of the Silent / Supersilent noise covers depends on the unit air volume. For pressure loss, refer to the technical data table.

Considering the unit output, always consult supplier or manufacturer of the heat pump or the cooling unit for the pressure reserve of the fans. For non-standard solutions, contacting the technical team of Stavoklima or an authorized technical office is recommended.
